2. What is Trash?
Defined: any matter that is no longer wanted,
worthless, useless and discarded.
Give some examples of trash?
What Happens to trash after it is discarded?
If trash is not disposed of properly were does it end
up?
3. Trash that is not
disposed of properly
ultimately ends up as
marine debris
Even if you do not live in a
coastal community all trash
makes its way to waterways
that lead eventually into
oceans
4. Marine Debris
Defined as human-created waste that is deliberately or
accidentally released into lakes, stream and oceans.
6. The debris get
collected in patches
These patches are filled
with many types of
hazardous material that is
dangerous to the health of
the oceans , marine life,
land animals and humans
around the globe. The
most famous patch is the
Great Pacific Garbage
Patch.
7.
8. Trash in the
Ocean
The Great Pacific
Garbage Patch is created
by two separate patches
that converge on each
other as gyre’s or a
massive whirlpool that is
created by the undersea
currents and the
movement of the earth.
11. Why should this concern me?
*Won’t the debris just decay and
become absorbed by the
environment?
From your list of what is litter or
trash list what you think is the
amount of time the piece of
garbage will biodegrade?

Notas do Editor
The following lecture will be provided in week 29/30 on Healthy Environment as stated in my yearly planner.
Elizabeth Kissam-Horaz
In the beginning of the lecture, which will be very brief, I will ask and define what is trash and each student groups of 3 will further elaborate on the 3 questions asked and place their answers on the board. After this exercise 3 handouts will be distributed 2 from NOAA (National Oceanic and Atmospheric Administration) on marine debris and one scholarly article for review.
Students will have a few minutes to review the material and prepare for further instruction.
Marine debris will be defined. This is the engage part of the 5e’s to science education. Students are given reading material and visuals from the power points to address the issue of marine debris which is beyond there knowledge and adds to what they already know about trash and recycling.
This slide with the prior slide will give graphic visuals and an up close view of garbage patches which is the outcome of not disposing of trash correctly.
Briefly lecture on the hazards of garbage patches to all living beings in the ocean and the earth and an introduction is made to describe the Great Pacific Garbage Patch. (allowing for the explore stage to be introduced)
Explore stage
Briefly the phenomenon of why this happens in the ocean is introduced (explore stage)
To bring to scale the garbage patch is compared to the United States so students may connect to the shear magnitude of the problem. (explore)
watch this video from NOAA on marine debris
Students will explain what they have learned by answering the questions on the worksheet that pertains to the video and the above questions will be discussed in class and students will elaborate on what they have learned. Further discussion will incur (engage, explore) and they will need to address biodegradability of trash.
